{"product_id":"hi-flow-sports-catalyst-cat-back-exhaust","title":"Hi-Flow Sports Catalyst Cat-Back Exhaust","description":"This downpipe features a larger diameter compared to stock components, which provides a more expansive pathway for exhaust gases to exit the engine, thereby boosting efficiency and power output. Paired with Milltek's Hi-Flow Sports Catalyst, it promises a substantial gain in performance and a more aggressive exhaust note.\n\nConstructed from aerospace-grade type 304, non-magnetic stainless steel, this downpipe is built for longevity and resistance to discoloration. The use of mandrel bending ensures consistent radius bends for optimized gas flow, and the enlarged bore diameters are meticulously calculated to maximize performance without sacrificing mid-range torque. Milltek's commitment to acoustic development ensures a sporty and crisp tone, free from undesirable NVH, drone, or cabin resonance.\n\nCrucially, a Stage 2 ECU remap is required for proper operation and to fully realize the performance benefits. Please note that the use of de-cats and sports cats, like this component, is intended for off-road\/motorsport use only and may inhibit your vehicle from passing a MOT test. Only EC type-approved components are legal and fit for road use.","brand":"Milltek Sport","offers":[{"title":"Default Title","offer_id":52689143824696,"sku":"SSXAU726","price":720.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687766255.jpg?v=1784902554","url":"https:\/\/store.motormia.co\/products\/hi-flow-sports-catalyst-cat-back-exhaust","provider":"MOTORMIA","version":"1.0","type":"link"}
